MY 2(0)C WORTH
Every so often I need to go to the hardware store to buy a fitting for a water pipe, a new seal for a tap, or the like. Inevitably the salesperson then asks if it’s a ½ -inch or ¾-inch fitting that’s needed. But how do you measure a fitting? Is it outside, inside, or the thread?
Fortunately, a kind salesperson gave me some very good advice: If a 20 c coin fits into the nut of the fitting, it’s a ½ -inch. If a R5 coin fits into the nut, then it’s a ¾-inch. It’s as simple as that! ( This only applies to metal fittings, though, not plastic.) Jakobus de Wet, Virginia
